This invention relates generally to tools. More particularly, it relates to the type of tools which are adapted for use in connection with the assembling and disassembling of cable iittings and cables.

One of the objects of this invention is to provide a tool of the character described having means for quickly removing a cable fitting from a cable, without injuring the iitting so that it may be again used in connection with another cable.

Another object of this invention is to provide in a tool of the character described, means for non-destructively removing a tting from a cable i in association with means for assembling a cable and iitting.

A further object of this invention is to provide a tool of the character described which is rugged in construction, relatively inexpensive to manufacture, which shall comprise few and simple parts, which shall be easy to assemble and to operate, and yet possess a high degree of eliiciency.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,

Fig. l is a side elevation, partly sectional, of an assembled device embodying my invention;

Fig. 2 is a plan view of the device illustrated in Fig. 1;

Fig. 3 is an enlarged detail sectional View taken substantially on the line 3 3 of Fig. 1;

Fig. 4 is a view taken substantially on the line 4 4 of Fig. l illustrating a portion of the device embodying my invention;

Fig. 5 is a View taken substantially on the line 5-5 of Fig. 1 illustrating still another portion of the device embodying my invention; and

Fig. 6 is an elevational View illustrating a cable and ttings in assembled relationship.

It has been found that cables of the type generally employed in flexible drive shafts for automobile, radio and for other similar uses, have a great variety of styles and sizes of cable fittings attached thereto suitable for speciiic purposes. Heretofore, whenever a cable wore out, or became defective for another reason, not only the cable (Cl. .Z9-33) had to be removed and replaced, but the ttings had also to be discarded, since they could not readily be removed from the cable without being destroyed in the process. Since, as previously explained, there are so many diiierent styles and sizes of these cable iittings in use that it is diiiicult at times to iind a dealer in such supplies, who carries all styles in stock. By means of my invention, I have devised a device which will quickly and non-destructively remove a cable litting from a defective cable, so that it Ymay again be used on a new cable.

My device, as disclosed in the drawing, comprises a base or support lil provided with a pair of upwardly extending ears, or bearing brackets Il and I2, which are aligned and spaced from each other. A rocker arm I5 is rotatably mounted, intermediate its ends, on a shaft i6 which is rigidly mounted in the brackets Il and l2. If desired, however, the rocker arm may be rigidly mounted on the shaft l5 and the shaft rotatably mounted in the brackets il and I2.

It is thus seen that the arm i5 isadapted to be rotated in either a clockwise or a counterclockwise direction. The rotational movement oi the rocker arm i5 is limited in both directions by contact of the lower surfaces i?, iS of the said arm, with the upper surface of the support l0. The said surfaces il, I8 maybe angularly inclined with respect to each other so that when either the surface ll or the surface |8 is in contact with the support surface it will be substantially parallel thereto.

Mounted onthe support lli is a pair of cooperating jaws 20 and 2|. One of the jaws, such as 2|, is provided with a notch 22 at one end thereof, and the other of said jaws 20 is provided with an outwardly projecting portion 23 at one end thereof which is adapted to be rcceived in the notch 22. The jaws 2i) and 2| are relatively movable toward and away from each other and are adapted to clamp a cable C of the character described between them. As shown in Figs. 1 to 3 of the drawing, the notch 22 of the jaw 2|, which is held stationary, is adapted to straddle the cable C, and the jaw 20 is moved toward the jaw 2| with suflicient force so that the projection 23'will press against the cable C to retain the same against vertical as well as lateral movement in the notch 22. Any suitable r means may be provided for moving the jaw 2i! toward and away from its cooperating jaw 2|, such as for example, slidably mounting the jaw 20, which may be trapezoidal in cross section in a'correspondingly shaped guideway 25 provided in the support I0. A screw threaded block 26 is fastened to the support Ill by such means as screws 21. Into the threaded portion of the block Y 26 is inserted a screw threaded shaft 28, one end Vcap 42 and a washer of which is adapted to abut against the movable jaw 2U. A'spring 30 is interposed between the jaws 20 and 2| which tends tol normally urge the jaw 20 in a direction away from the jaw 2|. It is thus seen that when the shaft 28 is rotated in one direction the jaw 20 will be slidably moved toward the jaw 2| against the action of the spring 3G, and when the shaft 28 is rotated in another direction, the jaw 23 will slidably move away from the jaw 2|, due to the action of the spring 3i). To` facilitate the rotation of the shaft 28 and in order toI obtain su'icient pressure on the projection 23 against the cable C a handle 29 may be attached to the free end of the shaft 28. While in the drawing I have shown a sliding bar type of handle, it is understood that any other suitable device may be employed, such as a fixed handle or a hand wheel, etc.

For non-destructively removing a cable fitting F from the cable C after the said cable has been clamped between the jaws 20 and 2| in the manner described above, I have provided a construction comprising a member 3| which is rigidly mounted at one end of the arm I5 for movement therewith. The said member 3| may be substantially semi-tubular in shape, as shown in the drawing, or of any similar desired form and provided with a bottom wall 32. The said bottom wall 32 is provided with a notch 33 which is adapted to register with the notch 22 when the bottom surface of the wall 32 contacts the top surface of the jaw 2| (see Figs. 1 and 3). The cable C is sol positioned between the jaws 20 and 2| that the bottom shoulder 35 of the tting F will contact the surface portion of the bottom wall 32 surrounding the notch 33. It is thus seen that when the rocker arm I5 is causedY to rotate in a counter-clockwise direction about the pivot I6, an upward force will be exerted on the shoulders 35 of the said tting F, to ultimately lift the fitting F off the end of the cable C, as illustrated by the dotted lines F in Fig. 1 of the drawing. To facilitate the counterclockwise rotation of the arm I5 and to provide sufficient `force for effectively removing the tting F as above describedy have provided the following mechanism:

Y Rigidly mounted on the support III is an upright rod 40 adapted to pass freely through an aperture 4| in the arm I5 and having the upper end thereof threaded. A cap member 42 having a screw threaded aperture 43 therein is provided which is adapted to Icooperate with the threaded portion of the rod 40. Interposed between the 44, said washer being designed to contact the portion of the arm I5 adjacent the aperture 4I, is a ball bearing device 45 of usual design in order to reduce the friction of the cap 42 on the washer 44. If desired, the arm I5 may be normally urged, by ymeans of a springV 46, to assume the position'where the .wall 32 will contact the jaw 2|, as shown in Fig. 1 of the drawing.

lIt is clearly seen from the above-described construction that as the cap 42 rotates in one direction, it will move downwardly tocause the washer 44 to rotate the arm I5 inra counterclockwise direction against Ythe action of the spring 43 and thus render the cable and fitting disassembling operation effective. To facilitate the rotation of the cap 42 and in order to exert a suiiicient downward force to rotate the arm I5, a handle may be provided which may be attached to the cap 42. While, in the drawing, I have shown a sliding bar type of handle, it is understood that any other suitable device may be employed, such as a fixed handle, or a hand wheel, etc.

The notch 22 and cooperating projection 23, are so designed that the cable C when gripped between them will not be weakened to such an extent as to cause breaking of the cable when the upward pulling force is applied to remove the fitting F. One way of effecting this result is to have the notch 22 of greater depth than the projection 23 and at the same time to bevel ofi all the square corners of the notch 22 and projection 23.

It has also been found desirable to disassemble cable ttings and cables without rst removing the casing 33 in which cables of the character described are customarily designed to operate. The said casing 83 is usually made shorter than the cable, allowing for a certain amount of free longitudinal sliding. This distance is in the nature of 1/4 to 1/2. Since it is desirable that the casing be not destroyed in the act of removing a cable tting it is seen that the cooperating jaws 2li and 2| as well as the bottom wall 32 of the above described pulling mechanism must not exceed in total space between the casing 80 and the bottom 35 of the filling F, as clearly shown in Figs. 1, 3 and 6 of the drawing.

Therefore, in order to meet all exigencies in non-destructively removing a cable fitting from a- 1" cable, the bottom wall 32 of the member 3| and the jaws 23 and 2| may be preferably constructed to aggregate in thickness approximately or less, but it is understood that this aggregate thickness may be varied if desired, in accordance with the relative lengths of the cable and cable casing. Y

In order to add to the eiiiciency and usefulness of my device, I have provided, in addition to the above-described disassembling apparatus, means for attaching a cable fitting to a cable.

My cable and fitting assembling apparatus comprises a pair of opposed jaws Eil! and 6I. The jaw may be rigidly mounted on the stationary support II), while the cooperating jaw 5I may be Vrigidly mounted on the rocker arm I5 for movement therewith. It is noted that the jaws are mounted on the opposite side of the pivot I6 from that of the disassembling apparatus, previously described, so that normally they will be disposed in open position as shown in Fig. 1, due to the action of the spring 4S. Each of the jaws Gil and 6| may comprise a semi-circular notched portion 62, having centrally located therein a projecting pin. In attaching the tting F to the cable C, the end of the said cable is rst inserted in the aperture 63 in the fitting F and then the neck portion N of the fitting is positioned in the notch 32 of the jaw 5I). The arm I5 carrying the cooperating jaw 3| is then caused to be rnoved toward the jaw I to clamp the fitting neck N between the jaws, by rotating the cap 42, in the same manner as hereinbefore described in connection with the disassembling operation. When suficient clamping force has been applied, the pins 32' will press to form a crimp t4 in the neck N to fasten the fitting F to the cable C, after which operation the cap 42 may again be rotated to spread apart the jaws'ill and 6I.

It has been found necessary at times to reduce thickness the above described I lil . movement, a support for said the diameter of the cable end in order that it may t into the tting aperture 63. I have therefore provided a pair of cooperating jaws E55 and S6 of any well-known suitable design for reducing the diameter of a cable end with one of the jaws, such as 655, being mounted on the stationary'support ii) and the cooperating jaw 66 being mounted on the arm i5. I have also provided a pair oi `cooperating jaws 6T and 68 for shearing or cutting the cable to any desired length or for trimthe ends of the cable before attaching a fitting thereto, the jaws El being mounted on the support Eil, while the jaw 58 is mounted on the arm i5. The pairs of jaws 65-i6 and iii- S8 may be suitably spaced with respect to the position of the pair of jaws ii-GL If desired, the three pairs of jaws just described may be adapted to be removed or replaced by pairs ofv jaws designed to accommodate different sizes of fittings and cables. It is also understood that, if desired, pairs of jaws may be added to eect other similar operations found to be necessary in connection with cables and ttings of the character described.

My device may be adapted to be fastened to a bench B or to any other similar supporting means by employing suitably positioned bolts 70 for attaching the member i!) to said bench B.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments set forth, it is to be understood that all matter herein contained, or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense.
